Specification of Letters Patent. Application filed February. 23, 1907. Serial No. 358,902.

Patented June 4, 1907.

To all whom it may concern:

Be it known that I, ARTHUR BAGGALEY, a

citizen of the United States, residing at 1 1635 Yale avenue, in the city of Chicago, county 5 of Cook, and State of Illinois, have invented a certain new and useful Improvement in Ventilators, of which the following is a speci-.

particularly to that 1 5 I therefore do not limit my invention to any particular class of structures or to any particular size or material.

The object of my invention is to construct a ventilator preferably of sheet metal, which is adapted to be placed over the tube which extends from above the lam in a car, through and above the top of t e roof, and which is affixed therein for the purpose of conducting the smoke and hot air from the lamp and car; that with or without such a tube, can be placed on the roof of cars orother structures requiring ventilation; that when placed in position on a car or other structure, by the deflection of the-current of air outside the ventilator will create a suction at the openings therein that will increase the draft through the ventilator; that will serve the pur ose ofa ventilator and smokejack on railroa cars; and that will prevent the en- 3 5 trance through the ventilator into the car of all cinders and dust.

The manner in which I accomplish my object is described in the following specification and illustrated in the accompanying draw- 40 in sinwhich:

igure 1 is a vertical central sectional view of the ventilator in position over a tube in the roof of a car, the point of view bein from the side of the car. Fig. 2 is a vertica sectional 4 5 view the point of view being from the end of the car. This view diflers from Fig. 1, in that an interior flan ed ring is shown aifixed to the interior of t e tube in the roof and the top part of a lamp is also shown; Fig. 3 is a. sectional planview on the line;33 Fig. 1.

Fig. 4 is a sectional plan view 0 "the line'44 Fig. 2. Figs. 5 and 6 are el vationswith parts broken away to show the deflecti curves of the plates which {forlm thebottom s 5 of the air ducts.

tube afiixed in the roof, this tube is preferabl cylindrical and may be straight or slig t'lytapering to a smaller diameter above the roof to afford an easy fit for the ventilator placed thereon. When these. tubes are in the roof of cars on which it is desired to place my invention, the ordinary smokejacks supported on these tubes areremoved and ase-' ries of holes are unched in the tube to corres ond with he es in; the ventilator to be p ac'ed thereon. The'main-part of my ventilator is a straight cylinder 0 which is adapted in size to fit friction tight on the tube B.

This cylinder is perforated near the lower end, the perforation C being adapted to register with the holes in the tube B, and the top of the cylinder extends some distance above the to of the tube B. Aifixed to the outside 0 the lowered e of the part C is an air duct D. This duct 1s formed of'four parts, a cylindrical partition D the vertical. part ofwhich is s aced -from the art 0 and extends upward a ove' the holes a cylindrical ar- .tition D the vertical portion of whic is s acedfrom the vertical part of the partition Il Between the vertical parts of the parts 1) and D ,and aflixed thereto are two.semi-,

circular deflecting plates D The ends D of 1 each' of these plates are arrangedin line with the lower edge of the vertical vpart of D. From these ends each plate curves u ward till the to edge of the vertical part of 13 as shown in Figs. 1 and 6. The ends D of eacli of these plates are spaced from each other to form the outlets D of the air duct D. These openin s, one on either side otthe ventilator are 0- cated sid'ewise of the length of the car as shown in Figs. 2, 3, 4, and 5. Aiiixed on the top of the cylindricalpart C "is another air duct E. This duct is formed of an outer top E and inner to E avertical cylindrical part E and two eflecting plates E. plates are affixed to the tops E and E and of the curve is in line with t e top These are curved and the ends E spaced from each other the same as in the duct D and the out lets of the duct E are located in the same direction as the outlets D The inner top E is perforatedto allow smoke and air toass from the interior of the part G into the not E. In the tube 3 is a curved'ringF which is I attached to the tnbe by the flange F. The

- lower edge of this ring is adapted in size to IIO panying drawings and secured in place on the roof of a car to serve as a ventilator and smokejack it produces the several currents of air which I will now describe.

When the ventilator is aflixed on. the roof directly over a lamp and provided with the ring F, the air from the interior of the car passes upward, between the tube B and ring F through the apertures C into the duct- D and out through the outlets D The smoke and heat from the lamp top G passes upward through the apertures in the inner top E into the duct E and out through the outlets E. The outside current of air enters the r 5 spaces D and E under the ducts D and E and is deflected by the curved plates D and E downward and past the outletsD and E. This deflection and movement of the outside air in a downward direction past the outlets of the air'ducts creates a suction proportioned to the speed of the current of air so deflected. This suction increases the natural draft of the ventilator in whichever direction the outer current of air may strike the venti- 2 5 lator. The location of the only exterior o enings D and E in the ventilator being sidewise of the length of the car the downward deflectionof the air from the interior of the ventilator, and the downward deflec- 0 tion of the outside current of air past these outlets, prevents the entrance into the ventilator and car through these outlets of cinders and dust. It is obvious that when my improved ven- 3 5 tilator is placed on stationary structures the outlets may be adjusted to the prevailing direction of the Wind over it; that on cars in which the lighting system produces no smoke or heat, the ring F may be dispensed with, 40 and that one or several ducts as the conditions may require can be made parts of my invention. It is also obvious that the deflectors forming the floor of the ducts D and E may be formed with, straight lines forming 4,5 an angle instead of the curved form shown and described the deflection of the air being substantially the same with either form.
